xorg server: major update 1.13.4 -> 1.14.3

- The 1.13 branch gets no updates since April,
  so I thought it's a good time to switch.
- Some xorg modules needed to be updated to build,
  but some don't have the update (probably all very obscure).
- Maybe it would be good to update the intel driver (or some others),
  I don't know.
polkit: remove hacks, fix chroot builds
Merge branch 'master' into x-updates
gtk2: minor update .20 -> .22
mesa: bugfix update 9.1.6 -> .7

Thist is just for master before the official release,
x-updates has 9.2.* already.

polkit WIP: TESTED OK, only missing NM config testing/tweaking

polkit WIP: resurrect the forgotten polkituser

It needs no group anymore. I hope it won't clash with leftovers from
previous usage of the user.
polkit WIP: enable forgotten config for NetworkManager

and only authorize "active" sessions.
dbus: minor update 1.6.14 -> .16 "fortify agility"
mesa: add GLES 1 and 2 support by default

The libs have just a few kilobytes and no additional deps.
mesa: bugfix update 9.2.1 -> .2

On 9.2.* we seem to be hitting a [problem] on Hydra
(unlikely to be fixed by this update),
although the tests run fine on my machine.

perl: avoid --no-cpp-precomp on darwin, (close #1160)

Taken from https://trac.macports.org/ticket/38913
vcunat renamed the patch

Conflicts (trivial):
	pkgs/development/interpreters/perl/5.16/default.nix
darwin x11/opengl: only copy subset of files (close #1165)

Copy only the pc files related to X11 and OpenGL.

This should allow us to build our own version of libraries like
cairo without having the native ones be accidentally dynamically
linked in to things that depend on them.

Before this patch if we `dyldinfo -dylibs libpangocairo` we can
see that it was dynamically linked against the OS X (but seemingly
built against include files from the nix one, as we would get a
runtime complaint about missing symbols)
mesa: disable checkPhase for the time being

The problem doesn't seem serious and it only occurs on some HW.
However, it would be best to fix this before merging into master.

I'm sorry I completely forgot to test the previous commit.
Also remove some long unused patch.
